How close is this construction to residential areas?June 12, 2020
What happens if you accidentally pierce a pocket of gas, oil or water during tunneling?June 12, 2020
During the design phase, there will be an exploration program to identify and detect buried and/or abandoned water, natural gas and oil wells to allow for removal of the wells prior to tunnel construction. During construction, gas detection methods will be used for flammable gasses. The mechanisms used for tunnel liner construction would provide a sealed work area and protect the boring machine and workers from water intrusions.
